Customers submit orders via web browser, FTP and Web Services. The system receives and validates the order, errors are sent to the appropriate CSR Team A credit check request is made, any areas of concern are sent to the appropriate CSR Team An inventory check request across multiple warehouses is sent, lack of availability goes to the CSRs. Assuming the order is valid, checks credit and available inventory, pick tickets are printed, shipping labels are printed, someone throws the parts into a crate or places on a pallet and puts the package by the loading dock. Various shipping companies are employed. Questions: [email protected]

An ESB Service is visible in the UDDI registry automatically. A single ESB Service may or may not expose a WSDL. It may use out-of-the-box actions, custom actions and/or consume external services from various sources. Focus on the reuse of existing infrastructure and assets. Questions: [email protected]
